Dear All,

I want to use biorad gene pulser for transforming *E. coli* with my ligated

It is mentioned in the bio rad manual that we must incubate the ligated mix
at 65deg C for 15 min to inactivate the enzyme and then proceed with its
dilution or etOH precipitation to get rid of extra salts that may decrease
the resistance and cause arcing.

I did go for the boiling step, but I'm afraid I'll lose the DNA by
precipitation since already only about 80 to 100 ng, insert + vector DNA is
present in my ligated mix. Cannot afford to lose any of it during

What could be done to get rid of the salt content that hampers the
